HEATING DEVICE.

Application filed April 30, 1923. Serial No. 635,484.

TocZZ whom it may concern:

Beit known that I, Josnrrr L. DONAT a citizen-ofthe United States, and a resident of the city of Chicago, in thecounty of Cook and State of Illinois, have invented certain new and useful Improvements in a I-Ieating'Device; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification;

This invention relates to heating devices, more particularly for household purposes.

It frequently happens'that one or more of the rooms in a house are insufficiently heated. Moreover, it is often the case that a chimney is located in one of the walls of such a room or passes up through such a room, up which'chimney a large amount of heat escapes.

One of the principal objects of the present invention is to provide means for utilizing a part of this heat, which now goes to waste, for heating the air in a room.

A further object of the invention is to provide means for varying the amount of heat transmitted from the chimney gases to the room. 7

It is also an object of the invention to provide an improved form of radiator.

Other and further important objects of this invention will be apparent from the disclosures in the specifications and drawings.

On the drawings:

Fig. 1 is a front elevation of a chimney radiator constructed in accordance with the present invention.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is a section on the line 33 of Fig. 2, and Fig. 4L is a horizontal section through a further form of construction.

As shown on' the drawings:

The radiator shown in Figures 1 to 3 inelusive comprises a casing 5 of U-shaped form, adapted to be insertedinto an aperture made in the chimney wall so that its outer face is substantially flush with the outer surface of the wall of the room. The chimney gases in passing upwardly through the chimney contact with the wall 6 forming the recessed portion of the casing, and impart heat thereto. In the interior of the casing is a chamber 8 for the reception and passage of the air to be heated, and to aid in the transference of heat through the wall 6 ribs 7 are arranged on both sides of these walls 6.

As it is desirable to be able to regulate chimney gases to the air in the room, means are provided for controlling the flow of air through the chamber 8 of the casing. For this purpose the front wall of the radiator is provided with inlet apertures 9 and exit apertures 10. Behind each of these openings are secured rectangular frames 11 2111C 12 respectively, within which are arranged a series of pivoted shutters or registers 13 and 1 1, adapted in a well-known manner to open and close these openings. Suitable operating means, such as pins 15 and 16, project through the front wall of the radiator, so that the position of the shutters may be adjusted as desired. In order to bring the air entering the radiator into better contact with the wall 6, which acts as the heat transferring surface of the radiator, a deflector or baiiie plate 17 may conveniently be arranged above the inlet openings so as to cause the incoming air to be deflected towards the rear part of the radiator.

To enable the chamber 8 of the radiator to be cleaned, an aperture 18 is provided between the air inlet and air exit apertures. This aperture 18 is normally closed by a door 19 hingedly secured at 2 0 to thefront wall 21 of the casing. A suitable latch 22 normally holds this door in closed position.

In order to clean those surfaces, of the radiator which contact with the chimney gases and which are, therefore, liable to become coated with soot, a portion of the inner wall of the radiator is formed of a plate 23 detachably secured to the adjacent portions of the casing by means of screws 24. In order to be able to reach these screws 24- for the purpose of detaching the plate 23, the front wall 21 of the radiator is also made separate from the other parts of the casing to which it is detachably secured by screws 25.

In front of the shutters or registers 13 and 14C ornamental grids 26 and 27 may be arranged as shown on the left-hand side of Figure 1.

In Fig. 4: is shown a further form of con-' struction adapted to be inserted in an aperture made in a corner of a chimney. In this case the chimney gases contact with the the amount of heat transmitted from the walls 30 and ribs 31 formed thereon, while the air to be heated passes through the chambers 32 in the casing. As in the previous form of construction, the flow of air through the chambers 32 is controlled by pi'votally mounted shutters 33.

It will be evident that where a chimney passes through a room out of contact with any of the walls of the room, an entire section of that chimney may be eliminated and in place thereof four sections, each similar to that shown in Fig, 4, inserted in its place.

I am aware that numerous details of construction may be varied through a Wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention: V

1. Aheatlng device comprising a hollow Ueshapecl cas ng adapted to be lnserted in an aperture in the wall of a chimney, the recessed portion of the walls of the casing being in contact with the chimney gases and means for alloyg in air to flow through the interior of the cas1ng 2. A heating device comprising a hollow U-shaped casing adapted to be inserted in an aperture in the wall of a chimney, the recessed portion of the walls of the casing being in contact with the chimney gases, vair inlet and exit openings in said-casing opposite said recessed portion ofthe walls, and

means for controlling the flow of air through one of said openings.

In testimony whereof I have hereunto subscribed my name in the presence of two subscr b ng W tnesses.
